From the early years of the twentieth century the development, first, of electronic instruments and then of other new ways of making, recording and transmitting sound, caused a rethink of the definition of the word ‘music’. Such developments led to some composers creating works that could not be adequately communicated through conventional notation. Various forms of graphic notation were adopted

This image, although it is primarily intended to be a visual abstract, suggests perhaps a relationship with graphic notation. Maybe you can imagine the mood and the qualities of sound the hieroglyphics and symbols suggest. I think Kandinsky might have been interested!
